BNYSTROM is right on the money, which makes sense given his/her occupation. Yes, much of the population are visual learners and there will always be a place for written instruction. Some are hands-on learners, which in situations that have been spoken of here, folk will need likely both written and visual instruction just to get them in there working with their hands and from there they figure it out as they do. Still there are three auditory learners whom do best with hearing detailed spoken instruction, which would take care of itself in a you tube video. Myself, I learn best by reading and writing. So written instruction with some high res pictures, like a power-point is the best way for me to accomplish/learn something. In fact, if it wasn't for over-head projectors (showing my age) and later power points I would have never gotten through school or college. So yes, written instruction certainly has a substantial place and should never be over-looked. Having said that, watching YouTube videos, even instructional ones are still really fun I think!
